How should I take this medicine?
Use exactly as directed on the label, or as prescribed by your doctor. Cold or cough medicine is only for short-term use until your symptoms clear up.
Do not take more of this medicine than is recommended. An overdose of acetaminophen can damage your liver or cause death. Taking too much diphenhydramine can lead to serious heart problems, seizures, coma, or death.
Some brands of acetaminophen, diphenhydramine, and phenylephrine are not approved for use in anyone younger than 12 years old.
Always follow directions on the medicine label about giving this medicine to a child. Do not use the medicine only to make a child sleepy. Death can occur from the misuse of antihistamines in very young children.
Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Dissolve one packet of the powder in at least 4 ounces of water. Stir this mixture and drink all of it right away.
Call your doctor if you still have a sore throat after 2 days, or if you also have a fever, headache, nausea, vomiting, or rash.
Stop taking this medicine and talk with your doctor if you still have a fever after 3 days, or you still have pain, stuffy nose, or a cough after 7 days (5 days if treating a child). Also call your doctor if your symptoms get worse, or if you have any redness or swelling.
If you need surgery or medical tests, tell the surgeon or doctor ahead of time if you have taken this medicine within the past few days.
